Asbestos

     Asbestos is the mineral smooth, the color of ashes white, who do not flammable. Asbestos worn in construction industry to protect from fire and to insulation, shipbuilding and trains, electricity, asbestos is very powerful and resistant heat, electricity and chemical. 





TYPE asbestos


There are three kinds of asbestos:


- Crocidolite: Blue asbestos. Multiple asbestos studies suggest crocidolite may be responsible for more deaths than any other type of asbestos because its fibers are so thin -- about the diameter of a strand of hair. When airborne, these fibers can be inhaled easily and become lodged in the lining of the lungs, more so than other forms of asbestos forms. Once inside the body, the fibers do not break down easily. This can lead to potentially life-threatening lung and abdominal conditions, including lung cancer, mesothelioma and asbestosis.


- Chrysotile: White asbestos. This is the most commonly used form of asbestos and can be found today in roofs, ceilings, walls and floors of homes and businesses. Chrysotile asbestos also was used in automobile brake linings, pipe insulation, gaskets and boiler seals. Although it is more prevalent, some studies show it takes more exposure to chrysotile than other types of asbestos to develop related diseases.


- Amosite: Brown asbestos. According to the American Cancer Society, exposure to amosite asbestos creates a higher risk of cancer in comparison with other types of asbestos. Several asbestos studies suggest exposure to amosite can cause lung cancer, mesothelioma and asbestosis. In its natural state, amosite is known as the mineral grunerite. Commercially, grunerite is referred to as amosite or brown asbestos. Approximately 80,000 tons of amosite were mined in the Transvaal province of South Africa by 1970.* All types of asbestos Dangerous, but the type of blue and Brown more Dangers Of The white. Frequently Used in the industry is a type of white asbestos 
     
     China has become a major producer and rivals Canada and Russia in terms of production of asbestos. In 2000, Russia led the world with 700,000 tons, followed by China and 450,000 tons from 335,000 tons from Canada. In 2000, the United States produces only some 7000 tons of mining in California and elsewhere, it is the entire world production of 2.13 million tons. Not surprisingly, Russia and China accounted for most of the consumption of asbestos followed by Brazil, India, Thailand, and Japan. United States used about 15,000 tons of asbestos in 2000, down from a peak of 750,000 tons per year in the early 1970s.
